Hubble Telescope finds Water Vapour on Habitable-Zone Exoplanet
For the first time have Astronomers have discovered water vapour signatures in the atmosphere of a planet beyond our solar system that resides in the habitable zone (the region around a star which can support liquid water given sufficient atmospheric ..
Scientists discover water vapor in atmosphere of a super-Earth “K2-18b”
For the first time, the astronomers at the University College London have discovered water vapour in the atmosphere of an Earth-size planet called K2-18b. They used data from NASA’s Hubble Space Telescope. The exoplanet “K2-18b” is 8-times the mass of ..
NASA discovers first nearby super-earth planet GJ357d
The NASA scientists have characterized the first potentially habitable world outside our own solar system that may be suitable for life. The super-earth planet — named GJ 357 d — was spotted by NASA’s Transiting Exoplanet Survey Satellite (TESS) mission. ..
The researchers at University of Warwick in UK discover a rogue exoplanet
The researchers at the University of Warwick in the UK have discovered a rogue exoplanet – NGTS-4b – with its own atmosphere in the Neptunian Desert. The Neptunian Desert is the region close to stars where no Neptune-sized planets are ..
TESS Mission of NASA discovers its first Earth-size planet – HD 21749c
The Transiting Exoplanet Survey Satellite (TESS) Mission of NASA has discovered its first Earth-size planet – HD 21749c. The newly-discovered planet is about 89% Earth’s diameter. The planet is likely very hot, with surface temperatures perhaps as high as 800 ..
Earth’s fate predicted: Newfound tiny planet gives a glimpse
The ground based telescope picked up signals confirming planet revolving sun like star. The star belongs to the Milky Way galaxy. The star was identified using spectroscopic methods. It is in its white dwarf state. Eventually our sun is also ..
Scientists discover new Saturn like planet 60 times bigger than Earth
Astronomers have discovered a new exoplanet using NASA’s exoplanet-hunting space telescope, TESS. The exoplanet is said to be 60 times bigger than our planet and is five-billion-year-old planet. The exoplanet is dubbed TOI-197.0 or “hot Saturn” because of its size ..
NASA finds superflares flares from Young Red Dwarf Stars imperiling planets
By using Hubble Space Telescope, the scientists of NASA have found that violent flares from the Young Red Dwarf Stars may make planets orbiting it uninhabitable by affecting their atmospheres. Hubble is observing such stars through a large programme called ..
